The photo -- which the "X-Men" actor simply captioned "Now that's what I'm talking about" as he gives a thumbs up while standing in front of what appears to be several grilled fish -- has him appearing with a grayish beard and noticeable lines scrawling across his forehead. It is a far cry from how the 47-year-old actor looked this summer while making a cameo appearance in "X-Men: Apocalypse."

But those concerns are likely unwarranted. Many noted that Jackman is likely in character for his upcoming untitled Wolverine sequel, where it's rumored he'll play an aging version of everyone's favorite X-Man.
